FASTENING MEANS FOR GRAIN DOORS.

Application led August 3, 1921. Serial No. 489,487.

T0 all whom t may concern Be it known that I, THOR RUsTAD, a vciti-` zen of the United States, residing atV Erskine, in the county of Polk and State of Minnesota, have invented a new and useful Fastening Means for Grain Doors, of which the following is a specification.

This invention relates to a Vfastening meansfor securing doors on grain cars.

An object of the invention is to provide a simple and reliable fastening means for grain doors which may be'applied without.

using nails or damaging or weakening the door or door post, and which will also form a brace to prevent bulging ofthe door.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing formingpart of this specification, with the understanding, however,`that the invention is not conined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modiications mark no material departure from n the salient features of the invention as eX- pressed in the appended Ink the drawing Fig. 1 is a side elevation of a grain car disclosing my improved door in position across the door opening of saidk car. 'Fig 2 is a plan view ofthe same.

claims.

Fig. 3 is a horizontal section of the door,l

disclosing a planr view of the adjustable f securing means on an enlarged scale.

' Fig. 4 is a view in detail partly in section, showing a modification of the fastening means. 1

In the drawing, 1 designates the side of a grain car having a side door opening 2, door posts 3, and a threshold 4. A. door 5 is adapted to extend across the side door opening 2, havingits ends 6 in engagement with the inner sides of the posts 3. The door may be made of any material ordinarily used for the purpose, and two or more of the door sections 4are usually positioned one above the other, as shown.,

The simplest form of fastening means for the door is disclosedat the left hand side of Figa 1 and 2 of the drawing, wherein a bar 7 having an eye.8 at one endV is looselyT and pivotally c onnecterlv to 'the door by means of a staple 9 secured to the door and engaging the eyef8 of the bar 7 The outer end of the bar 7 is adaptedtol abut the side a brace.

10 of the door post 3, the bar 7 thus forming an angle with the door and acting as This bar is reinforced by flanges 11 and 12 extending in opposite directions from the upper and loweredges, respective ly, of said bar.

Near its outer free end, the bar 7 is provided with a notch 13 in its upper edge, in which is adapted to be seated a nut 14 providedwith an operating arm ,15. A hook 16 having a screw-threaded shank 17 engages the internally threaded opening of the nut 14, the hook vitself engaging th staple 9a secured in the door` 5. f

The nut 14 has a countersunkportionp14,

thereby providing a space between the nuti and the-'threaded shank 17 of the'hook 16,

so that the head 17a 'located upon the outer end .of the shank 17 of the hook 16 may be ymoved within the countersunk portion.

The head 17a being unable to pass by the inpreventthe hook 16 from becoming disengaged from the| nut 14.

-ternally threaded bore ofthe nut 14, will.

ing means described above, with the bars 7 engaged by the staples 9 at one end and at its other end abutting the side 10 of the door postv 3, no provision' would be made e for different width doors. i v

' Since all doors are not' of the same width, it is necessary to provide some form of adjustable means for positioning one of the bars 7 along the door, and this is shown at the right hand side of Figs. 1 and 2. and on an enlarged scale, Fig. 3. I provide a bar 18 slidably and'loosely mounted within a slot 19 formed in the door 5. The slidable bar 18 is provided at one end with a perforated lug 20vwhich is looselyengaged by the hook 16, the perforated lug 2 0 serving the .same function as t-he staple 9? previously described. The other end of the bar v18 is likewise provided with a perforated lug' 21 which is loosely engaged by a hook 22 formed upon one end of the bar 7, the per-y forated lug 21 replacing the staple 9 of the locking device at the left hand side. The inner edge of the slidable bar 18 is provided with a lug 28 projecting outwardly and downwardly from a point on the bar 18` near the perforated lug 21. The lug 23 is adapted to overhang the edge of the slot 19 in the door 15 to relieve the hook 22 of ak certain amount ofv pressure and also to Cri tioned adjustable means and engaging the pivoted bar at a point between its ends for securing the door. the irst-menticned adjustable means being provided with a lug which. is adapted to engage one oli' a series of teeth on the door to lock the iirst-mentioned adjustable means in position.

6. A car door, means connected at one end to the door and extending outwardly at an angle to said member and al'iutting at the other end a door post7 and means loosely connected with said door and engaging the first-mentioned means at a point between its ends to secure said door1 to the car.

7. A doorymeans pivotally connected with the door and engaging a door post, and means connecting the door with the pivotally mounted means at a point between the ends of said pivoted means.

8. A door, a bracing means `for the dooi` to prevent bulging of the door, and means loosely connected with the door and engag` ing the bracing means and cooperating therewith to loclr the door inA position.

9. A door, a bar pivotally mounted on the door and abutting a door post, a hook loosely connected with said door and provided with a screw-threaded shanln and a nut-"adjust-` able on the threaded shank of the hook and engaging the bar to force the free end of the bar into engagement with the door post to lock the door. j

10. A door, an adjustable bar.v slidably .mounted in a slot in the door, a bar pivotally connected at one end to an end of the adjustable bar and having its free end in abutting relation with a vdoor post7 a hook loosely connected with the other end of the adjustable bar, means `on-the hook and engaging the pivotally mounted bar forV drawing the door towards the pivoted bar, and

means on the adjustable bar and engagingv the door to prevent displacement of said bar from the slot in the door.

1l. A door, an adjustable bar slidably mounted in a slot in the door, a bar pivotally connected at one end to an end of the adjustable bar and having its free end in abutting relation with a door post, a hook loosely connected with the other end or the adjustable bar, means on the hook and engaging the pivot-ally mounted bar for drawing the door towards the pivoted bar, a rack bar secured in the slot of the door, and means on said adjustable bar adapted to engage the rack bar to prevent displacement of the adjustable bar.

12. A door,lan adjustable bar slidably.

Ubar in opposite directions.

13. Ina door7 a bar havingits ends engaging respectively the door and a door post, an internally threaded sleeve provided with a counterbore concentric with but larger in diameter than the threaded. borez aVscrew-threaded rod engaged in the threaded bore, and having` a flared end located within the counterbore, andmeans connecting the combined sleeve and rod with the bar and door said sleeve and rod being rotatable relative to each other to lock the door to the door posts.

14:. In a door, a bar having its ends enrespectively the door and a door post, an internally threaded sleeve provided with a counterbore concentric with but larger in diameter than the threaded bore, aho'olr depending` from the end o said sleeve and engaging a staple mounted on the door, a screw-threaded rod engaged in the threadwithin thev counterbore, means on the other end of said rod :tor rotating the same, and means on said rod adapted to engage the bar to draw the door up firmly to the door post when said rod is rotated.

K In testimony, that I claim the foregoing as my own, I have hereto affixed my signature.
